IMHO, it is about time lens manufacturers improve their overall quality and at the same time, set reasonable prices. All of the pixel peepers can crow about who's the top dog in the camera market, but if the quality of available lenses is not up to the challenge, then all of this is just a waste of time. I for one am sick to death of ridiculous prices (and poor performance ) of most lenses. I do not understand why it should cost as much as a top tier camera body every time a "good" lens is released. C'mon... How can the camera makers hope to sell their newer models if so many of us cannot afford to "upgrade" our lenses to get the performance we pay for?
